Purest form of carbon is diamond….
Carbon is the 15th most abundant element in the Earth’s crust and the fourth most abundant element in the universe by mass.
All known form of life has carbon.
Charcoal is the dark grey residue consisting of impure carbon obtained by removing water and other volatile constituents from animal and vegetation substances.
Charcoal is usually produced by slow pyrolysis, the heating of wood or other substances in the absence of oxygen. The resulting soft, brittle, lightweight, black, porous material resembles coal.
http://en.wikipedia.org/wiki/Charcoal
Activated carbon is a form of carbon that has been processed to make it extremely porous and thus to have a very large surface area available for adsorption or chemical reactions.
Activation/Oxidation: Raw material or carbonized material is exposed to oxidizing atmospheres (carbon monoxide, oxygen, or steam) at temperatures above 250 °C, usually in the temperature range of 600–1200 °C.
Chemical activation: Prior to carbonization, the raw material is impregnated with certain chemicals. The chemical is typically an acid, strong base, or a salt (phosphoric acid, potassium hydroxide, sodium hydroxide, zinc chloride, respectively).

Assigned to Division 4.2 – Spontaneous Combustion.
Self-heating substances, which are substances, which, in contact with air without energy supply, are liable to self-heating. These substances will ignite only when in large amounts (kilograms) and after long periods of time (hours or days). If the rate of heat production exceeds the rate of heat loss, then the temperature of the substance will rise which, after an induction time, may lead to self-ignition and combustion.
A substance shall be classified as a self-heating substance of class 4.2 as per tests performed in accordance with the test method given in the United Nations Manual of Tests and Criteria, part III, 33.3.1.6
CARBON animal or vegetable origin – 4.2 1361
CARBON, ACTIVATED – 4.2 1362
1361 PG II & III / SP 925 and 223 for PG III
1362 PG III / SP 223 & 925
SP 925 states
The provisions of this Code do not apply to:
– non-activated carbon blacks of mineral origin;
– a consignment of carbon if it passes the tests for self-heating substances as reflected in the UN Manual of Tests and Criteria (see 33.3.1.3.3), and is accompanied by a certificate from a laboratory accredited by the competent authority, stating that the product to be loaded has been correctly sampled by trained staff from that laboratory and that the sample was correctly tested and has passed the test; and
– carbons made by a steam activation process.
When Charcoal/ Carbon is considered as non Hazardous?
a) Either it is non-activated carbon blacks of mineral origin; or
b) Passed the UN test as per SP 925; or
c) carbons made by a steam activation process
MSDS must contain either of the information in ‘a’ or ‘b’
Or
Shipment must be supported/accompanied by test report in ‘b’
Shipping lines may have individual house rules with varying conditions for acceptance of hazardous and non-hazardous carbon.
Dear sir,
We are ready to export ” wood based granular steam activated carbon ” .
It is DG or NON DG.
Pls confirm the same.

Hello sir
We planned export coconut shell charcoal which is produced from pit method .whether it comes under hazardous. Some people claims steam activated coconut shell charcoal what is the differences between steam activated coconut shell charcoal and non activated one.
Which is the lab in south India which carry test on coconut shell charcoal and issue certificate of non hazardous.
Is MSDS support by lab certificate
Since we are manufturer cum merchant trader ,can we issue MSDS For manufactured and traded (produce from pit method by small farmers)material.
With out non hazardous certificate ,what is the procedure for export.
Regards
Prasad
Dear Mr. Prasad,
Please send me the MSDS and details of your production method to my mail shashi@shashikallada.com

Hi Shashi,
I work as a FF, and recently I received an enquiry to ship charcoal in a 40FT. But none of the carriers I approached, want to handle the shipment because it is a dangerous and will dirty the container.
Any advise on who I can approach to help me ship?
Thank you
Anuja,
Can you send your cargo details to my email. shashi @ shashikallada.com

Dear Mr Shashi
Our company produces Activated Carbon as a by-product when Ilmenite and Coal is heated in a kiln to a temperature of approximately 1100C. The coal is used as a heat source and reductant for the Iron Oxide on the Ilmenite.The carbon produced is activated but can we claim that it is “steam activated” it is certainly not “chemically activated”. Can you explain how Gas phase activated carbon is produced ?
Good Day,
Ideally to call “steam activated” we need presence of steam in activation process. Your carbon is neither chemically activated. Hence self do not think you can get exemption to ship it as non-hazardous unless tested and proved.
Regards/Shashi
Dear Mr. Shashi, I am working actually for a worldwide shipping line, thanks for your good article, but talking about vegetal burnt shell, it remains to me one doubt that SP925 does not mentions at all,
all and every lot of goods must be subject to the self-heating evaluation according SP925 or just a minimum sample of a, let´s say, 200 tons of product to be shipped in different maritime containers, is enough?
In other words, is the validity of the self-heating evaluation for a specific period and one product or just a unique use.
Thanks beforehand
Dear Javier,
Apologies for delay in replying.
Test shall be conducted by randomly picked up samples by a laboratory accredited by the competent authority. Even though IMDG Code does not say about validity period for this test we should proactively re test the product if we suspect the properties may have changed due to exposure to humidity, wet weather etc.
Laboratory personnel shall be the best people to advise you on this regard.
Regards/Shashi
Dear Mr. Shashi,
Thanks for your reply.
As you say, IMDG nothing says regarding the validity period for a specific product, but this would not be a excuse for a manufacturer for keep shipping his stuff using just one test issued let´s say two or three years ago.
To avoid problems I saw that some countries ( Argentina ) legally speaking standardizes this fact forcing to pass one SP925evaluation to samples of every lot to be shipped.
Most of the vegetal burnt shell are manufactured and exported from Indonesia. Is there some specific regulation in respect of the frequency of the self-heating evaluation there? Are you maybe mindful of that or where to find this regulation?
Thanks a lot
Dear Javier,
I am not aware of any specific regulations or frequency requirement for self heating test imposed by Indonesian Competent Authority.
If you represent a line you may look upon to revise your own in house restriction with such or similar requirement to ensure correctness of classification and stability of such products.
You must be more alert when carrying “so called” non-hazardous charcoal.
Regards/Shashi
Dear Mr. Shashi,
thanks for your kind reply. It is quite useful for me.
Last, why did you say that about the “so called” non-hazardous charcoal?
regards
In some cases charcoal offered as non-hazardous has run into self ignition. Coconut shell and other charcoal being offered as non-haz must be thoroughly vetted by scrutinizing lab test report, report results against UN test criteria, whether lab is authorized by competent aithoruty etc.
further shipping line may ask shipper for indemnity and include such provisions in B/L to safeguard line’s interest.
regards
Many times charcoal offered as non-hazardous had run into self ignition which is the reason for me to state that one must be cautious about charcoal offered as non-hazardous if same is not supported by test reports.
Regards/Shashi
can you pls confirm what is segrigation group from D Aci Mono sodium salt
You need to check with the manufacturer whether D Aci Mono sodium salt has any property to fall under a particular segregation group or more.

hi shashi,
thanks for the informative article!Seeking your assistance on my inquiry.What If the commodity is granulated charcoal (from Coconut shell)? Will these be acceptable as non-hazardous?
MSDS indicates that comoodity is under UN no. 1361
Self heating test reports are as follows:
Self heating test, 140 C @ 100 mm cube: positive
Self heating test, 140 C @ 25-mm cube: negative
Self heating test, 120 C @ 100 mm cube: negative
Dear Nessa,
If MSDS shows the commodity as UN 1361 why do you consider to transport as Non-hazardous ?
Charcoal need to be tested as indicated in United Nations Manual of Tests and Criteria, part III, 33.3.1.6 and depending on the result it may not be classified as Class 4.2.
Regards/Shashi
i need this certificate from the lap
self heating Charcoal

Sohil, You need to contact the Competent Authority of your country to find which lab is authorized to conduct this test.

Good and Informative for Exporter Like me… Thanks, Also please confirm once again that Activated carbon can be declared Non Hazardous if it is Steam Activated.
Thanks
